Connector with a connection detecting function

A connector, comprising:

• a first housing (10);
• a second housing (40) connectable with the first housing (10);
• at least one force multiplying member (24) provided displaceably on the first housing (10), the first and second housings (10, 40) being connected by displacing the force multiplying member (24) engaged with the second housing (40);
• at least two detection terminals (13) provided in the first housing (10);
• at least one shorting member (19) in the first housing (10) and displaceable in a direction intersecting a displacing direction (DD) of the force multiplying member (24) between a releasing position (RP) where the detection terminals (13) are released from a shorted state and a shorting position (SP) where the detection terminals (13) are shorted;
• a biasing means (17) for biasing the shorting member (19) toward the releasing position (RP);
• and
• a pressing surface (29) formed on the force multiplying member (24) and being substantially parallel with a displacing direction (DD) of the force multiplying member (24) and adapted to displace the shorting member (19) to the shorting position (SP) in a partly connected state (PCS) where the first and second housings (10, 40) are partly connected while permitting a return of the shorting member (19) to the releasing position (RP) when the first and second housings (10, 40) reach a completely connected state (CCS).
